New Catalysts for Chemical Isotope Exchange between Water and Carbon Dioxide

The results of a study of the activity of catalysts for the reaction of catalytic isotope exchange between carbon dioxide and water vapor are presented. The samples were synthesized on the basis of iron, cobalt and nickel oxides, applied to a carrier—γ-aluminum oxide. The results of structural studies of the obtained samples were analyzed using scanning electron microscopy, X-ray fluorescence analysis, and low-temperature nitrogen adsorption to determine the specific surface area and porosity. It was concluded that nickel oxide supported on aluminum oxide has the highest catalytic activity (observed rate constant k = 5.49 ± 0.36 s –1 ).
